Abstract
Diabetes mellitus more often called diabetes is a chronic condition that raises levels of glucose in the blood because the body cannot produce any or enough of the hormone insulin or use insulin effectively. When left untreated, high levels of glucose in the blood continue and cause damage to various body organs, leading to the development of disabling and life-threatening health complications. Unfortunately, no cure has been found for diabetes at this moment. However, these serious complications can be prevented or delayed with appropriate management. Current methods of insulin delivery require multiple daily injections or continuous subcutaneous insulin infusions, causing a delay in insulin absorption and possibly creating an infection. These disadvantages can be solved with an implanted device. However, only implantable insulin devices introduced required a large battery inside the body. The purpose of this research is to design an implantable insulin pump that is small and uses untethered control through the ferromagnetic soft material actuator and magnetic field generator for control. This device consists of a balloon, ferromagnetic soft material, two check valves, and an insulin reservoir. Externally, the battery-powered magnetic field will be created to deform ferromagnetic soft material and squeeze the balloon to inject insulin. The ferromagnetic soft material is fabricated and magnetized for controlled deformation, by controlling balloon deformation with an accurate external magnetic field, precise insulin injection is possible without any of the discomfort that current insulin delivery devices give. In this research, the major objectives are to design of battery-less implantable insulin pump using a ferromagnetic soft material, create a profile between the magnetic field and fluid flow, construction of system and test for its accuracy and precision. Finally, test data will be compared with the FEM simulation date. This will show the feasibility of this implantable insulin pump design
